Abstract:

The patent describes an optical communication system including a device for splitting the output beam from a laser into two quadrature polarized beams, phase modulators for modulating at least one of the two beams, and a combiner for thereafter aligning the two means in a noninterfering manner for transmission along a single path. The system further includes a receiver for receiving and separating the two transmitted beams, a rotator for axially re-aligning the polarized beams, and a combiner for combining the two beams in an interfering manner thereby causing amplitude modulation of the combined beam. The signal information is then removed from the amplitude modulated beam by a detector and fed to any suitable readout device.
